How we helped

Under our fully funded Power Purchase Agreement (PPA) model, Zestec supported Kärcher in beginning their energy transition to lower their carbon impact and reduce their energy bills, through generating their own onsite renewable electricity. After a detailed survey and due diligence, Zestec’s partner, Solar Perfect, designed and installed a 300 kWp solar PV system. Since completion c.75% of the solar energy generated onsite has been consumed by Kärcher, representing c.201,000 kWh per annum.
